CO 2减排已经成为国际关注的热点问题。近年来，化学吸收法以其效率高、适应范围广、技术成熟等优点，逐渐占据主导地位。采用甘氨酸钠溶液为吸收剂，在超重力反应器中进行了CO 2吸收实验，考察了转速、吸收液温度、吸收液浓度、气液比等对CO2吸收率的影响。结果表明：CO2的吸收率随着转速的增加而上升，当转速达到1000 r?min?1后，吸收率基本趋于稳定；CO 2的吸收率随着吸收液温度的升高而升高，在90℃时可以达到83%以上；在实验范围内， CO 2的吸收率随吸收液浓度的增加略有增加，随气液比的增加而逐渐降低并趋于稳定。

Carbon dioxide emission reduction has become a hot issue and attracted international attention. In recent years, chemical absorption methods gradually dominate the market since they have advantages of high efficiency, widely adaptation and mature technologies. CO2 absorption experiments were conducted in a rotating packed bed using aqueous sodium glycine as a solvent. Effects of rotational speed, concentration and temperature of absorption solution, and gas-liquid ratio on CO2 absorption efficiency were investigated. The experimental results indicate that the absorption efficiency of CO2 increases with the increasing of rotational speed and the absorption efficiency becomes stable when the rotational speed is 1000 r?min?1. The absorption efficiency of CO2 also increases with the increase of absorption solution temperature, which can reach to over 83% at 90℃. Under certain operation conditions, the absorption efficiency of CO2 increases slightly with the increase of absorption solution concentration, while it decreases first and then becomes a constant with the increase of gas-liquid ratio.
